Crystal Ballroom (above), originally built as Cotillion Hall, is a historic building in Portland,Oregon. Cotillion Hall was built January 21, 1914 as a ballroom, and dance revivals were held there through the Great Depression. Starting in the 1960s, the hall has also been host to many popular pop, rock, folk, blues and jazz artists, as well as beat poetry and other entertainment.

It was originally owned by Montrose Ringler who lost the ballroom in the early 1920s. Dad Watson then bought the building in the mid-1920s, when mostly square dances were held during that time.After Watson’s death in the 1930s, Ralph Farrier bought the ballroom and renamed it the Crystal Ballroom. The venue continued hosting square dances through the 1950s.
